Wang Su's daughter, Wang Yuanji, married Sima Zhao and gave birth to Sima Yan, the first emperor of the Jin dynasty (265–420). Wang Su inherited the title and marquisate of Marquis of Lanling (蘭陵侯) from his father.[4]

Wang Su compiled the extant edition of the Kongzi Jiayu (School Sayings of Confucius), the sayings of Confucius not included in the Analects. Scholars long suspected it was a forgery by Wang Su,[2] but a book discovered in 1977 from the Shuanggudui tomb (sealed in 165 BCE), entitled Ru Jia Zhe Yan (儒家者言, Sayings of the Ru School), contains very similar content to the Kongzi Jiayu.[5]
